Question by TVG33K · Jun 26, 2017 at 08:37 PM · collidertriggerplayerrange

Repeat While Object in Range

I am using a version of Unity 4, kind of old, I am looking at updating it. I am a beginner still and I have barely learned the old version, the new version seems just that much more complicated. My code has a sphere collider on an enemy, and I want it to constantly take 1 health from the player while the player is within the enemies circle. I turned the sphere to "On Trigger", it doesn't work. here you go.

 public class MogiAI : MonoBehaviour {
 
     public GameObject player;
 
     public float MovementSpeed = 2;
 
     public bool IsMoving = true;
 
     bool Triggered = false;
 
     public float testhealth = 100;
 
 
 
     // Use this for initialization
     void Start () {
 
     }
     
     // Update is called once per frame
     void Update () {
         if (IsMoving == true){
             transform.position = Vector3.MoveTowards (transform.position, player.transform.position, MovementSpeed * Time.deltaTime);
         }
         transform.LookAt (player.transform.position);
         if (Triggered == true) {
             testhealth = testhealth - 1;
                 }
     }
 
     void OnTriggerEnter (){
         Triggered = true;
     }
 
     void OnTriggerExit (){
         Triggered = false;
     }
 
 }

First, check the signature of OnTriggerXXX : https://docs.unity3d.com/ScriptReference/$$anonymous$$onoBehaviour.OnTriggerEnter.html

Then, make sure the collisions are detected (using Debug.Log) if not, follow carefully the tutorials on the Unity website.

You must attach a Rigidbody to the player and set its Is Kinematic checkbox to make it visible to triggers: a kinematic rigidbody is visible to the physics engine but doesn't react to forces, collisions, gravity etc.
NOTE: By the way, your player will drop dead in one second or less if you subtract 1 from its health every Update. Multiply the health loss per second by Time.deltaTime in order to get a constant speed:

 if (Triggered == true) {
              testhealth -= 2 * Time.deltaTime;  // player loses 2 units per second
 }
